The atomic transition gives rise to the radiation of frequency `(10^(4)HMz)`. The change in energy per mole of atoms taking place wiould be:

`3.99xx10^(-6)J`

`3.99J`

`6.62xx10^(-24)J`

`6.62xx10^(-30)J`

Text Solution

Verified by Experts

The correct Answer is:

`E=Nhv`
`=6.023xx10^(23)xx6.626xx10^(-34)xx10^(4)xx10^(6)=3.99J`
